GLASS-CUTTERS BOARD.

SPECIFICATIONforming part of Letters Patent No. 714,545, dated November 25, 1902.

d Application filed June 25, 1902. Serial No. 113,125- (No modeldescription.

This invention relates particularly to improvements in attachments for glass-cutters boards, the object being to provide a simple means for holding the straight-edge 011 the glass to be out, also permitting the straightedge to be moved to any desired part of the board and moved to any desired angle and to swing upward from the board when it is desired to place glass thereon or to remove the same. i

I will describe a glass-cutters board embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan View of a glass-cutters board, showing the attachments embodying my invention as applied thereto. Fig. 2 is a side elevation. I Fig. 3 is a section on theline 3 3 of Fig. 1. Fig. 4: is a detail plan View to illustrate the angular adjustment of the straight-edge. Fig. 5 is a section on' the line 5 5 of Fig. 3. Fig. 6 is a sectional detail showing the straight-edge in resting position. Fig. 7 is a detail showing the limiting-stop for the back movement of the straight-edge.

Fig. 8 is a section on the line 8 8 of Fig. 9, and Fig. 9 is a section on the line 9 9 of Fig. 8.

Referring to the drawings, 10 designates a cutting-board marked off in inch-scale lines in the usual manner. Mounted to swing vertically and to rotate at one edge of the board is a guide-rod 11. This guide-rod has bearings at its ends in'sockct members 12 of arms 13, pivotally connected to plates 14, attached to the board. To limit the downward movement of the arms 13 relatively to the plates edge 16. This straight-edge is provided at its rear end on the upper side with a metal bearing-plate 17, which has a sleeve 18 extending through an opening in the straightedge. The straight-edge rests upon and is designed to be clamped to a sweep-plate 19, to which are attached collars 20, which engage the guide-rod. Also engaging around the guide-rod between the collars 20 is a clam pin g-collar 21. This clamping-collar has a screw-threaded stem 22, which passes upward through the sleeve 18 and is engaged by a nut 23. Pivotally connected to this nut 23 is a clamping-lever 24:. This clampinglever has eccentric portions 25, which engage against opposite sides of the nut 23 and are pivotally connected thereto, as clearly shown in Fig. 5, and these eccentric portions also engage upon the bearing-plate 17.

The sweep-plate 19 is provided with an arc slot 26, through which a clamping-bolt 27 passes. This clamping bolt also passes through an opening in the straight-edge and on its upper end is engaged by a thumb-nut 28. Obviously by this construction and as the straight-edge turns on the stem 22 the said straight-edge may be firmly clamped at any desired angle over the board, of course parallel with the board.

As the straight-edge is moved along the board the clamping-lever is to be turned upward to relieve the pressure of the clampingcollarOn the guide-rod. After moving the straight-edge to its proper position the clamping-lever is to he turned downward, as indicated in Fig. 8, which will firmly clamp the straight-edge in its adjusted position.

By pivotally connecting the arms 13 to the plates 1 1 the straight-edge may be swung upward, so as to accommodate it to any thickness of glass that may be on the board. Then it is desired to remove a plate of glass or place one on the board, the straight-edge may be swung upward by the rod turning in its bearings, as indicated in Fig. 6, and to prevent its swinging too far rearward I provide on one end of the guide-rod a stop device, here shown as a finger 29, attached to a collar 30, mounted on the guide-rod, and designed to engage with a bracket portion 31 of the arm 13. This collar is adjustable around the shaft and may be held as adjusted by a set-bolt 3... On the front edge of the board is a stop or guide-strip 33, and on an edge at right angles to said front edge is another guide-strip 34. As shown in Figs. 8 and 9, these guide strips are mounted to yield vertically with relation to the board, so that their upper edges may be moved downward flush with the top of the board when a pane of glass larger than the board is placed thereon, but when in upper position they will serve to guide and square the glass on the board. The guides are mounted to move between the edges of the board and strips 35, which are secured to the board by means of screws 36. These screws pass through slots 37 in the lower edges of the guides, and the guides are pressed upward by means of springs 38, which engage against the lower sides of the guides and against the portions 39, extending inward from the strips 35 and secured to the bottom of the board.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a glass-cutters board, a guide-rod mounted to rotate at one edge of the board, a sweep-plate movable along the rod, a straightedge, a clamping-collar engaging around the rod and having a stem extending through an opening in the straight-edge, and a clampinglever connected to said stein for engaging upon the upper surface of the straight-edge.

2. In a glass-cutters board, a guide-rod at one edge of the board, the said guide-rod being mounted to rotate and to swing upward with relation to the board, a straight-edge adjustable along the rod, and means for clamping the straight-edge in its adjusted position.

3. In a glass-cutters board, arms mounted to swing at one edge of the board, a guide-rod having rotary connection with said arms, a straight-edge adjustable along the rod, and means for clamping the straight-edge as adjusted.

4. In a glass-cutters board, arms mounted to swing at one edge of the board, means for limiting the downward movement of said arms, a guide-rod having rotary connection with said arms, a sweep-plate having an arc slot, collars attached to said sweep-plate and through which the rod passes, a straight-edge having openings, a clamping-bolt extending through the slot of the sweep plate and on said clamping-collar, extending through the other of said openings in the straight-edge, a nut on a threaded portion of said stem, and an eccentric lever pivoted to said nut.

5. In a glass-cutters board, a guide rod mounted to swing vertically and to rotate at one edge of the board, a stop-finger carried by said rod, for limiting its rotary movement, a straight-edge adjusted along the rod, and means for clamping the straight-edge in its adjusted position.

6. In connection with a glass-cutters board, plates attached at one edge thereof, fingers extended from said plates, arms pivoted to the plates and adapted to engage with said fingers for limiting the downward movement, a guide-rod mounted to rotate in said arms, a straight-edge adjustable along said rod, and means for clamping the straight-edge in its adjusted position.

7. In connection with a glass-cutters board, a guide-rod at one edge thereof, a sweep-plate having collars engaging around said rod, the said sweep-plate being adjustable along the rod and having an arc slot, a straight-edge having openings, at clamping-bolt extended through said are slot and through one of said openings, a clamping-collar engaging around the guide-rod, a threaded stem extended from said clamping-collar and through the other of said openings, a bearing-plate on the upper side of the straight-edge, a nut on the stem, and a clamping-lever having eccentric portions pivoted to said nut and adapted for engagement with the bearing-plate.

8. In connection with a glass-cutters board, spring-actuated yielding guides arranged at edges of the board.

9. In connection with a glass-cutters board, a strip arranged at an edge thereof, a guidestrip arranged between the first-named strip and the edge of the board, and springs for holding the said guide-strip yieldingly upward.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ARTHUR THOMAS WHITEHOUSE.
